Abstract

The present invention provides a cargo-carrying truck integral front spring right front support working process which comprises the following steps: two side surfaces of the right end is milled; the convex mesa of the left end is milled; the upper mesa is milled; a channel is milled; the inclined surface is milled; all small holes are drilled and countersunk; all large holes are drilled and reamed; the bottom hole of each screw hole is drilled; the deep mesa is milled; each screw hole is tapped. The machining process of the present invention has the advantages that each machining step is scheduled reasonably, positioning and clamping of work pieces are facilitated, the accuracy requirement for the work pieces can be ensured, and the machining efficiency is high.

Description

Cargo-carrying truck integral front spring right front support working process

Technical field

The present invention relates to the processing technology of the preceding right front support of spring of heavy motor truck monoblock type, belong to machine components technology field.

Background technology

Present general assembling semiellipse formula leaf spring on heavy motor truck one bridge and two bridges, this spring and be fixed on vehicle frame on the spring support utilization before the form of hanging after cutting with scissors be connected.The preceding right support of right support and two springs is separate hinged with spring eye and hanger respectively behind traditional preceding spring.Vehicle in motion, owing to user overload, road conditions difference and reasons such as a bridge and two bridge resonance, these two support force more complicated often occur and the phenomenon of vehicle frame mutual dislocation, the accident that support ruptures also happens occasionally.For addressing the above problem, right support before right support behind the preceding spring and two springs is integrated, can form the right front support of spring before the high monoblock type of a good reliability, bulk strength height, packing precision, can improve the steering behaviour of vehicle.For the right front support of spring before making monoblock type reaches required precision in process, need to formulate the special processing technology of a cover, also there is not such technology at present.

Summary of the invention

The present invention is directed to the right front support of spring before the above-mentioned monoblock type, a kind of efficient height is provided, can guarantees the cargo-carrying truck integral front spring right front support working process of required precision.

For achieving the above object, the present invention adopts following technical solution:

Before this cargo vehicle monoblock type the right front support of spring by preceding spring after before right support and two springs right support be integrated and form, its machining process is:

(1) mills the left end two sides;

(2) mill the right-hand member boss face;

(3) mill upper table surface;

(4) mill out shelves;

(5) mill the inclined-plane;

(6) bore each aperture of ream;

(7) bore each macropore of expansion hinge;

(8) bore each hole bottom outlet;

(9) mill deep mesa;

(10) each hole tapping.

Each procedure arrangement of technical process of the present invention is reasonable, is convenient to workpiece location and clamping, can guarantee the required precision of workpiece, the working (machining) efficiency height.
